They have the same electron configuration as argon, which means they are isoelectronic with argon.
Arranging in increasing size: Cl- < S2- < K+ < Ca2+. Arranging in increasing ionization energy: K+ < Ca2+ < Cl- < S2-. Electron configurations: Cl-: [Ne]3s^2 3p^6 S2-: [Ne]3s^2 3p^6 K+: [Ar]4s^1 Ca2+: [Ar]4s^2
They all have stable electron configurations, either full outer shells (Argon) or filled electron orbitals (Sodium, Chlorine, Potassium, Calcium). This stability makes them chemically unreactive or less likely to form compounds under normal conditions.
Both calcium ion (Ca2+) and argon atom (Ar) have a full outer electron shell, making them stable and unreactive. This stable electron configuration is achieved by either gaining or losing electrons to attain a full valence shell.
calcium is normally [Ar] 4s2 if it is a 2+ ion, then it has lost 2 electrons so the configuration is just [Ar]
Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, with 18 electrons.
They have the same electron configuration as argon, which means they are isoelectronic with argon.

No, potassium (K) in its K2+ cation form and calcium (Ca) have different electronic configurations than argon (Ar). Potassium has an electron configuration of [Ar] 4s1 and calcium has an electron configuration of [Ar] 4s2. In contrast, argon has an electron configuration of 1s2 2s2 2p6 3s2 3p6.
Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, with 18 electrons.
Cl & K ions are isoelectronic with Ar.
Chlorine ions - gain an electron to be - 1s2, 2s2, 2p6, 3s2, 3p6 same electronic configuration as Ar
